IMPROVED BED-BOTTOM.

TO ALL WHOM IT'MAY CONCERN:

Be. it known that I, BEECHER HITCHCOCK, ot'- Waukegan, in the county of Lake, in the Stateot' Illinois, i have invented an Improved Bed-Bottoni; end I do hereby declare that the following is a. full and exact descripti'on thereof, reference being' had to the accompanying drawings, and to vthe letters of reference marked thereon, making a part of this specification, in which- Figure 1 isa longitudinal elevation of my bed-bottom. y

Figure 2, a top view of the same, Withan end rail broken away t show the width of the springs.

- The nature of my invention consists inthe use o^fsteel springs, having ditterent lengths and curves, for

the support of the top frame ot` a common spring-bed bottom, and in arranging thein so as that the head' ofthe bed will sustain a `greater weight than the foot, whereby apersons head may rest at the proper height without extra holsters, notwithstanding the preponderance ot' the upper part of the body. i

In order to give a correct understanding` ofmyinvention, I have marked. corresponding parts 'with similar letters, and will now give a. detailed description., t t

A represent-s the upper and B the lower frame ot tlie common springfbed bottom. C Gis one'of the Springs used for the support of the sides of the trarne A, us seen at g. 1, and is secured to frame B by means of bolts F F, and to frame A by staples E' E. -This spring is made ot' cast steel, and with the part C, supporting the foot ofthe bottom, longer than the partfG, supportingr the headliner-der that the latter may always'remain the highest when in use, and also inndepwith lthe ends D curved downward, to provide suitable surfaces for them to slide through the staples EE, and against the`under side of frame A, when it is made to have a vertical reciprocatingr motion. t I Y The spring II is used for the head of the bed, and is made and secured the sa-me as'spring C G, only its ends from the bolts ls` F are of the suino length, in order that '.thefends of the bottom may be kept as near parallel as possible. i

The spring I, supporting the foot ot` the bed, is made about one-third longer than the s-pringat the head,

by which means the frame A will incline toward the tootwhen the weight is equalon all parts of the top, but will he about level when u person lies, thereon. Y'

The staples E E are covered with leether, a d, in order to prevent any noise, which would otherwise occur if the curved ends D D were permitted to strike against bare metitl. i

It will be seen from 'this description that the springs'not onlyanswer the purpose herein described, but will also prevent the frame A from having ai longitudinal and laterulrnotion, and, tixrther, provide a simple, cheap, :indiconvenient means for supporting the upper traine.`

I do not claim the application of semi-elliptical .spring to bed-bottoms, but

What Ido claim, and desire to secure by Letters Patent, isV y The arrangementvot` :t longspring, I, for the foot of frames A B, und e. short spring, H, for their heads, in combination with side springs, having long,r arras, C, and short arms, G, substantially as and for the purpose set-forth.

BEECHER HITCHCOCK.
